Hello all, I have a question about network sharing. I have a MacBook Pro, connected via ethernet cable, and I use it as a hotspot to connect other devices via wireless. Obviously, the wireless network is protected with WPA. Even so, in the Finder window, under the Shared heading, I see the names of 3-4 pcs, most likely belonging to my roommates. How is it possible? They deciphered the hotspot password? Thank you for any replies.
